    [0001] In recent years, the solutions relating to the autonomy of a watch mechanism have been a family of complications in themselves.
    For more than two centuries pocket watches or wristwatches are content with autonomy, which was called default "power reserve", an average of 72 hours, to such an extent that these 3 about days of power reserve have become a standard.
    We can say that there are two ways in mechanical watches to accumulate energy to increase the autonomy of the mechanism.
    The first is to multiply the number of barrels, that is to say containers of mechanical energy, the barrel consisting of a drum containing a steel spring-blade wound on itself in a spiral and which, when this blade is concentrated in the center of the drum, is ready to deploy and release its energy that feeds a cog for the running of the mechanical watch for the duration of its operation, so its autonomy.
    The second solution is to increase the size of the barrel drum, more precisely to increase the volume receiving a steel leaf spring considering that the volume available in this container is directly proportional to the accumulated energy.
    In this document, we consider that the term "power reserve" is synonymous with full autonomy, that is to say the duration of the complete winding of the watch until the end of the -this.
    [0007] In the past, it has been considered that it is essential to use high oscillation frequencies of rockers, for example 21,600 vibrations per hour or 28,800 vibrations per hour, in order to be able to to obtain correct chronometric performances. The frequencies currently used the most in watchmaking are those of 21,600 vibrations per hour and 28,800 vibrations per hour. More than 90% of Swiss mechanical movements use these two frequencies. There are also known parts whose oscillators operate at a frequency of 36,000 vibrations per hour.
    But at these frequencies, the moving speeds of the moving elements are such that the clock mechanism thus produced becomes extremely delicate, both in development, assembly, manufacture and scope. It will be understood very easily that the more moving parts are solicited, the faster they will wear out.
    [0009] Contemporary mechanical watchmaking must be satisfied by a compromise between the precision of the watch, the lifetime of the components and the overall autonomy, all under the guise of quality assurance so as to guarantee that this watchmaking mechanism will operate. at least for the next ten years.
    In break with this evolution of precision research via a high oscillation frequency of the balance, the present invention allows an increase in the accuracy of the watch and an increase in autonomy, while greatly reducing the frequency of the balance.
    Object of the invention
    The invention consists in combining two technologies in the same clock mechanism or, more accurately, to use quartz technology for precision, the mechanical watch technology for the accumulation of energy, all without the need. to change the batteries of the watch and thus keep the visual appearance of a mechanical watch.

The system includes:a device for blocking the movable element, the locking device being able to present a blocking state of the movable element and a release state of the movable element, anda computer, in particular a computer comprising an auxiliary oscillator such as a quartz or a resonant electrical circuit or a resonant electronic circuit, the computer being able to successively control the blocking and release states.
    It should be noted that, preferably, the locking device does not block or immobilize the mobile element as soon as it is in a blocking state. Preferably, the blocking device blocks or immobilizes the movable element when it is in a blocking state and the movable element reaches a particular or determined position.

    The appended drawing represents, by way of example, an embodiment of the subject of the invention.<tb> Fig. 1 <SEP> is a diagram of an embodiment of a timepiece according to the invention.<tb> Fig. 2 <SEP> is a flowchart of an embodiment of a method of operation of a clock controller system according to the invention.
    An embodiment of a timepiece 400 according to the invention is shown in FIG. 1. It comprises a movement 300, in particular a mechanical movement. Preferably, the mechanical movement comprises a source of mechanical energy such as a barrel and a mechanical oscillator such as a balance spring oscillator.
    Advantageously, the movement comprises a counting wheel including a counting seconds wheel, the counting wheel being arranged so that the seconds counting wheel performs a movement corresponding to a duration of 0.5 seconds, or even 1 second, or even 5 seconds, or even 10 seconds, or even 30 seconds when an escape wheel moves one step.
    Advantageously, the movement comprises a counting wheel including a counting minute wheel, the counting wheel being arranged so that the minute counting wheel performs a movement corresponding to a duration of 10 seconds or 20 seconds. seconds, or even 30 seconds, or even a minute when an escape wheel moves one step.
    The movement comprises a watch mechanism 200 including a watchmaker system 100 and a clockwork escapement 20.
    The watch regulator system 100 for a watch movement includes a mobile rocker 1 relative to a frame 2, the system comprising:a device 4 for blocking the mobile element, the locking device being able to present a blocking state of the mobile element and a release state of the mobile element, anda calculator 5, in particular a calculator comprising an auxiliary oscillator 51 te! a quartz or a resonant electrical circuit or a resonant electronic circuit, the computer being able to successively control the blocking and release states.
    The system advantageously comprises an actuator 6, in particular an electromagnetic or piezoelectric or magnetostrictive actuator. The actuator is arranged to control the state of the blocking device. The actuator is arranged to be controlled by the computer. Indeed, the actuator allows for example to radially move the locking device relative to the balance.
    The locking device comprises a first stop 7 provided on the balance and a second stop 8 secured to a frame of the system. The first and second stops are intended to cooperate with each other by obstacle.
    The second stop 8 may comprise a plate 41 on which is fixed a flexible blade 42 at a first end 43 of the blade. The plate 41 also comprises, near a second end 45 of the flexible blade 42, a pin 44 against which the flexible blade comes into contact when it is not stressed. The second end 45 of the flexible blade cooperates with the first stop 7 provided on the balance to immobilize it. The actuator 6 may be provided to move only the flexible blade 42 of the second stop. The plate can then remain fixed relative to the frame 2.
    The computer 5 is for example mounted on the movable member or on the frame.
    The balance and the frame may comprise electromagnetic elements arranged so as to convert the kinematic energy of the mobile element into electrical energy.
    In the embodiment described, the movable element 1 is a pendulum. However, the movable element may be of a different nature. It can be an exhaust wheel blocker, including an anchor, or an escape wheel or a mobile of a finishing train or a barrel.
    In the embodiment described, the second stop is displaced by the actuator 6. Alternatively, the locking device may comprise a deformable portion of the movable member, in particular deformable under the effect of an electric field or of a magnetic field.
    The central point of the invention is to reduce the frequency so that an oscillation of the balance until the next oscillation, there is a time for example of one minute. It is of course impossible in the usual dimensions of a watch to design a pendulum and its exhaust that would take 30 seconds to make a go, that is to say an alternation, and 30 seconds to return, that is to say say another alternation. The size of such a pendulum would be totally disproportionate. To achieve this goal, it is resorted to means that stop the pendulum movements for a certain time.
    For this purpose, it is possible to use a stop-second device. This notion of stopping the pendulum exists in watchmaking, it is called the "stop-second" function. Such a device is used when it is desired to stop the movement of the needles, especially the seconds, during the time setting. The stop-second device is able to act on the balance to immobilize it. In this way with the use of a stop-second, it is possible to bring the seconds hand to a certain place of the time-indicating dial and press a button, for example to stop and restart the balance of a watch.
    In the invention, automatic activation and deactivation means of such a device, in particular a stop-second device, are implemented. For example, mechanical means located outside the oscillator, for example on the plate, can mechanically stop the pendulum. A calculator, including a calculator incorporating a quartz oscillator, placed in the watch mechanism accurately counts the time and an electronic circuit manages the time between two stop and start orders of the oscillator.
    It is as if between the first "Tic-Tac" and the "Tic-Tac" following, for example exactly 60 seconds waited. The 60 seconds is the time it takes for the minute hand to advance one notch or so in its minute display.
    Throughout the exhaust system, the anchor also has a pendulum back and forth movement. His period is the same as that of the oscillator. Also in this escapement, the escape wheel (also called anchor wheel) which usually has between 15 and 21 teeth, moves in a rotational jerk movement with of course as many jerks as there are alternations in the oscillator and as the escape wheel is directly connected by a gear train to the display of hours, minutes and seconds, one can observe very distinctly the saccades due to alternations of the oscillator at the end of the oscillator. the seconds hand.
    We can say that this second hand "beats". In general, it beats having as many beats between each second indication that there are alternations of the oscillator. In still the same example of a 5 Hz oscillator, since there are 10 alternations per second, the end of the seconds hand will beat at 10 beats between each second.
    At the level of the escape wheel, the advance or the movement is of the unidirectional incremented type, that is to say advancing step by step, tooth by tooth, beat by beat. One can more easily say that a watch indicates the second or that it beats the second. In a watch, the second hand has a rhythm of a number of beats per minute depending on the frequency of the oscillator.
    All this, we usually use the following frequencies:A 2.5 Hz oscillator can be recognized at 5 beats / second on the second hand and therefore has 18,000 vibrations / hour.A 3 Hz oscillator can be recognized at 6 beats / second on the second hand and therefore has 21,600 vibrations / hourA 3.5 Hz oscillator is recognizable at 7 beats / second on the second hand and therefore has 25,200 vibrations / hourA 4 Hz oscillator can be recognized at 8 beats / second on the second hand and therefore has 28,800 vibrations / hourA 5 Hz oscillator can be recognized at 10 beats / second on the second hand and therefore has 36,000 vibrations / hour
    Some attempts at higher frequencies between 7 and 10 Hz have been made, but these are more trials associated with research than commercial products.
    Functioning of the mechanism
    In order to implement the regulator system, we can use an escapement type "Swiss anchor". As in this kind of escapement the escapement wheel, that is to say the escape wheel, advances one tooth at each oscillation, it can therefore be assumed that at each oscillation, that is that is to say once a minute, the escapement mobile angularly advances a step, that is to say a tooth.
    A pinion mounted integral with the escapement mobile transmits this angular movement to another mobile so that a tooth of the escape wheel corresponds to the indication of one minute on the mobile driven by the mobile exhaust.
    The source of mechanical energy, that is to say the barrel of the watch or the set of barrels, is raised by conventional means, either manual or automatic.
    In a conventional watch the barrel meshes directly with a mobile center in most cases. In the case of the invention, the barrel can mesh directly with a mobile carrying the minute hand. A clockwork called timer can cause a wheel of hours quite conventional arranged concentrically or not the mobile minutes. The watch incorporating a regulating system according to the invention can have a quite conventional appearance. The time setting can be performed by a conventional time setting system of a mechanical watch.
    By cons, compared to a conventional watch movement in a watch movement according to the invention, all or part of what is called the gear train, or the wheel train, is eliminated. It can be reduced to or replaced by a center wheel, driven directly by the barrel drum, and in turn driving an escape wheel pinion.
    The escape wheel of the mobile exhaust actuates the anchor of the exhaust that transmits the movements in a completely conventional way to the balance, via for example a double tray, that is to say via the plateau pin, positioned under the balance and allowing it to receive the energy giving it its alternating movement.
    The oscillator itself is equipped with a simple hairspring, preferably without any racking, that is to say without the need for adjustment of the active length of the hairspring.
    For this system to operate at a very low frequency, that is to say for example at 120 vibrations per hour, that is to say 0.01666 Hz, the regulator system comprises a device allowing stop the pendulum, for example towards its end of alternation, this moment being perhaps the best since the angular velocity of the pendulum is null or weak or, towards the beginning of the following alternation, when the balance starts again. This device comprises for example a pendulum stop system. This device can act as a stop-second device. At this point, a calculator counts the time required via an auxiliary oscillator such as a quartz to determine when the balance will be released again so that it performs an oscillation. After this oscillation, the pendulum is stopped again.
    Thus, in one embodiment of the method of operation of a regulator system according to the invention:it releases (step 510) the balance which has been previously stopped towards the end of its alternation so that it can start alone in its next alternation thanks to the force stored in the spiral;the pendulum is blocked near the end of its alternation;the time is counted thanks to the computer 5 and, after a certain time, the order, via an actuator 6, is given to the stop blocking device 7, 8 to release the balance,the above steps are repeated.
    In the computer, an electric or electronic oscillator, optionally quartz 5 may be equipped with a divider circuit and a control element 6. The computer determines the operation of the pendulum locking device which allows the blocking and releasing the movement of the balance 1 or any other movable member located between the balance and the motor of the watch mechanism. The alternations of blocking and release of the balance 1 are made at a controlled position for optimum restart of the latter. The sum of the blocking and releasing times represents a constant time interval whose accuracy is defined by the computer and adapted to the display mechanism.
    Any stop-second device could be suitable for implementing the invention, since it can be activated and deactivated on command of the computer.
    However, we prefer a stop-second device for stopping the pendulum in a specific position, including a position in which the spiral spring is constrained. Thus, it is possible to limit the time during which the device is configured in a release state to allow the restart of the pendulum.
    In case of immobilization of the pendulum in any position there will be a doubt about the degree of movement of the pendulum which will have been achieved during a given period of time when the locking device is in the released state before it again blocked.
    An exemplary embodiment of the operating method is shown in FIG. 2.
    According to this example, the following steps are iterated.
    Assume the moving element initially immobilized.
    In a first step 510, the blocking device is passed from a blocked state to a released state. Thus, the moving element starts moving. In particular, the balance is set in motion by the action of the hairspring. The passage can be achieved by displacement under an action of the actuator 6 of the abutment 8, in particular a displacement away from the abutment 8 of the movable element. In fig. 1, the stop 8 moves for example to the right. This movement may comprise a displacement of the flexible blade relative to the plate 41. The flexible blade is then no longer in contact with the first stop and the rocker starts moving. In fig. 1, the first stop then passes under the flexible blade.
    In a second step 520, a time counter is initialized.
    In a third step 530, the timer is triggered.
    In a fourth step 540, it is tested whether the time counter has reached a determined time Time_1. If this is not the case, we go to step 540. If this is the case, we go on to a fifth step 550.
    In the fifth step 550, the blocking device is passed from a released state to a locked state. Thus, the movable element will be immobilized as soon as it reaches a determined position of cooperation of the stops 7 and 8. The stop 8 may comprise or consist of a flexible blade. The passage can be achieved by displacement under an action of the actuator 6 of the abutment 8, in particular a displacement bringing the abutment 8 of the movable element. The stop 8 then moves for example to the left to return to its position shown in FIG. 1. This movement may comprise a displacement of the flexible blade relative to the plate 41. Thus, the first stop 7 approaches the blade until coming into contact therewith. Under the effect of the inertia of the balance, the action of the first stop causes a bending of the blade from its first end 43 until the first stop passes over the blade. Once the first stop is above the blade and the first stop comes back against the blade, it is immobilized because the blade is less flexible because it rests against the pin 44.
    Note that although the rocker is released from a contact position of the first stop against the blade, it returns to a position beyond this contact position because of the energy it received from the exhaust 20 during the two alternations traveled.
    In a sixth step 560, it is tested whether the time counter has reached a given time Time_2. If this is not the case, we go to step 560. If this is the case, we go to step 510.
    The transition from the blocked state to the released state is achieved at regular time interval.
    It will also be noted that the natural frequency of the mechanical oscillator, in particular the natural frequency of the sprung balance has very little importance in the embodiments according to the invention. Indeed, this natural frequency must only be greater than the inverse of the period Time_2. Thus, for time_2 period values equal to 1 second and 1 minute, the eigenfrequencies of the oscillator must be greater than 1 Hz and 0.17 Hz, respectively.
    Preferably, as previously seen, according to the invention, the movable element is immobilized at each oscillation of the movable element or once by oscillation of the movable element. To do this, the duration Time_1 must be less than the proper period of the moving element.
